Now I know this has nothing to do with boyfriends but ye I checked my heart beat before after sitting for 1 Hour and it said I am 160 bpm( beats per minute) now I am a cheerleader and a gymnast so I am pretty healthy and I go to a sports collage also I am 13 year old girl So what I'm getting across is that I am worried my heart beat is pretty high should I be worried or is this about right? Help me
